WRAPPER-PASTER.

SPECIFICATION forming part of Letters Patent No. 459,269, datedSeptember 8, 1891.

Application filed February 26, 1891. Serial No. 382.853. (No model.)

To aZZ whom it may concern:

Be it known that I, DAVID WALLACE CoL- mm, of the city and county ofPhiladelphia, and State of Pennsylvania, have invented a new and usefulImprovement in rapper- Pasters, of which the following is a full, clear,and exact description.

This invention, while applicable as a pasting apparatus forotherpurposes, is more particularly designed to be used for applying thepaste to newspaper and other like wrappers, and to aid in packing thepapers in wrappers, and it will here be described accordingly.

The invention consists in a novel device I 5 or apparatus forautomatically supplying the paste and laying it on the part of eachwrapper to be pasted, and in certain constructions and combinations ofdetails in such a device, substantially as hereinafter described, and

more particularly pointed out in the claims.

By means of my invention much labor is saved and the papers or otherprinted matter may be put up in wrappers with greater ease, rapidity,and accuracy; also, space is economized and the whole operation isaltogether cleanly, there being no scatteringor dropping of paste.

Reference is to be had to the accompanying drawings, forming a part ofthis specification,

in which similar letters of reference indicate corresponding parts inall the figures.

Figure 1 represents a front elevation of the apparatus applied to a pileof newspaperwrappers. Fig. 2 is a vertical section of the same upon theline 2 2 in Fig. 1. Fig. 3 is a plan view thereof, and Fig. 4 is a Viewin perspective of a slide used to regulate the size of thepaste-discharge opening, or to shut off the flow of paste when required.

A indicates a metal or other suitable pan for holding the paste, andwhich is of a length or a little more than the length of the width ofthe wrappers to be pasted. Said pan otherwise may be of any suitabledimensions and is made to taper downward at its sides, the lower marginsof which are turned in and a discharge-opening Z) made in the bottom ofthe pan of the length, or thereabout, of the pan and of a width tofurnish a film of paste, or whatever the adhesive material may be, to orin excess of the widest area of wrappermargin to be pasted. ithin thebottom of the pan is soldered or secured a second bot tom .9, of tin,brass, or other suitable material, having a series of perforations c init over the discharge-opening Z) in the lower bottom of the pan. By thiscombination of the perforated upper bottom and longitudinally-aperturedlower bottom the paste, which may be thickened or thinned to secure aproper flow, is automatically delivered in a thin unbroken or perfectfilm to the pasting-margin of the wrapper lying underneath it but tomore perfectly regulate the flow of the paste to the wrapper to suitlarge or small wrappers and to altogether shut off the flow whenrequiredas, for instance, when replacing one pile of wrappers for afresh pile-I apply to the under side of the pan a hand-slide B,which mayhave its ends turned up to slide in creases or grooves in the ends ofthe pan, and which has alongitudinal slot or opening (Z in it,preferably of lesser width than the opening I) in the bottom of the pan.Accordingly as this slide is ad- 3' usted the width of the discharge forthe paste is increased or diminished, or by adjusting it to Wholly closethe opening I) the flow is wholly shut off.

The pan A, with its attachments, is hung or supported by projections e eon its ends to So freely rise and fall within upright slotted standards0 C, secured at theirbase by screws or nails to a board D of anyconvenient size.

In this way the pan or its attached slide B is made to rest upon and tofollow down the pile 8 5 of wrappers E as they are consecutively used upone at a time, in packing the papers. The wrappers are introduced inapile at their closing or pasting marginal portions over the board D andunderneath the pan, each suc- 9o ceeding pile consisting of any suitablequantity of wrappers. Each wrapper maybe separately lifted by theoperator moistening his finger upon a dampened sponge and be drawn outfrom beneath the pan, suitable pressure being applied. to hold theremaining wrappers in the pile, and the paper or papers folded up in thewrapper and the latter tabbed or directed in the usual or any suitablemanner.

Ordinarily--that is, for light wrappersthe I00 weight of the pan withits attachments and contents will be sufficient to secure the necesgiveadditional pressure.

and an inner bottom provided with a series Having thus described myinvention, what I claim as new, and desire to secure by Letters Patent,is

1. In awrapper-paster, a pan adapted to contain the paste or adhesivematerial within it, having a longitudinally-apertured bottom ofperforations over the aperture in the lower bottom, for operationsubstantially as described.

2. In a wrapper-pastel, the combination, with the paste-holding panhaving a longitudinally-apertured bottom and an inner bottom providedwith a series of perforations over the apertures in the lower bottom, ofan adjustable paste-discharge-controlling slide arranged beneath thelower apertured bottom of the pan, essentially as specified.

3. In a wrapper-paster, the combination, with the automatically-loweringpan which holds and automatically supplies the paste to a pile ofwrappers beneath, one at a time, and the end standards adapted to guidesaid pan in its descent, of adjustable arms or weights pivoted to thestandards and adapted to throw downward pressure on the pan or to berelieved from exerting pressure thereon as required, essentially as setforth.
